Omak Creek Road Decommission
Omak Creek, tributary to the Okanogan River, contains natural reproducing steelhead, federally listed as "endangered". However, past land management activities continue to impair aquatic habitat in Omak Creek. Unnaturally high amounts of fine sediments occurs throughout the stream, but are excessive in reaches within the upper watershed. Roads were identified as the leading factor for increased sediment yield within the Omak Creek watershed (NRCS 1995).
Road density within the Omak Creek watershed is conservatively estimated at approximately 6.35 miles/square mile (NRCS 1995). To reduce the deleterious effects of the high road density, a "ripping" technique has been implemented on road surfaces to allow infiltration and decrease the amount of sediment delivered to stream channels.
During 1999 approximately 38 miles of roads within the Omak Creek watershed were closed and decommissioned. To continue this effort, an additional 20 miles of road in the upper watershed area of Omak Creek were recommended to be decommissioned. Road sections will be selected through an inter-disciplinary team and based upon location, condition, and utility.
Monitoring will include measuring volume of fine sediment in pools. These measurements, conducted post road decommissioning, will be compared to baseline data collected during 2000.
